Can I Make Concrete with Just Sand and Cement?

2020-8-13  Image by jarmoluk via Pixabay. Just as you can make no-fines concrete without sand, you can create a concrete mix that incorporates a high proportion of sand. However, concrete that incorporates higher levels of sand compared to coarser aggregates will be weaker overall and cannot be used for structural applications or where support or load-bearing abilities are required.
